in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
Abstract. Information on forage quality in phenological stage could help range managers to choose suitable grazing method to achieve higher animal performance without detriment to vegetation. Vetiver grass (Vetiveria zizanioides) is a non-native perennial grass that was introduced to the Iran in 2008. This plant is a multi use species that could be considered from different viewpoints. Thus, it...
For determination of grazing capacity, information of forage quality is essential which is influenced by various factors. The main objective of this research was investigation on effects of species, phenological stages, and life form on values of forage quality indices of six range species. Species were two grasses (Bromus tomentellus and Dactylis glomerata), two forbs (Ferula ovina and Coronil...
throughout this dissertation r is a commutative ring with identity and m is a unitary r-module. in this dissertation we investigate submodules of multiplication , prufer and dedekind modules. we also stat the equivalent conditions for which is ring , wher l is a submodule of afaithful multiplication prufer module. we introduce the concept of integrally closed modules and show that faithful mu...
introduction oxidative stress is an inevitable consequence of intensive production due to mismatched balance between free radical production and natural antioxidant capacity of animals. reactive oxygen species (ros) refers to a group of free radicals produced by oxidative energy cycle and also recently demonstrated to be as a weapon for macrophage cells. moreover, feed processing phenomena such...
Determination of forage quality of plant species in natural habitats such as rangelands and deserts is one of the most important factors for grazing management of these ecosystems. For this purpose, the nutritional values of Calligonum comosum in three phenological stages (vegetative growth, flowering, and seedling) were determined in desert habitats located in the northeast of Kashan, Iran (in...
there are two major theories of measurement in psychometrics: classical test theory (ctt) and item-response theory (irt). despite its widespread and long use, ctt has a number of shortcomings, which make it problematic to be used for practical and theoretical purposes. irt tries to solve these shortcomings, and provide better and more dependable answers. one of the applications of irt is the as...
this dissertation has six chapter and tree appendices. chapter 1 introduces the thesis proposal including description of problem, key questions, hypothesis, backgrounds and review of literature, research objectives, methodology and theoretical concepts (key terms) taken the literature and facilitate an understanding of national security, national interest and turkish- israeli relations concepts...
